Abstract

The effect of 500, 2500, 12,500 and 62, 500 r of X-rays on several constituents of germinating barley has been studied. Such doses inhibit the increase in RNA, DNA, protein, acid soluble, and soluble N content. The acid RNase activity varies proportionally to the RNA content, except in the coleoptile, where irradiation greatly enhances the frequency of an abnormal distal region rich in RNase and poor in RNA. The origin of this enzymic activity and the interpretation of our results
are discussed in relation to the possibility of interference of translocation mechanisms with the normal synthetic processes.
